Question 8.
120(1 + 0.02)2 ____________
Answer:
Given,
120(1 + 0.02)2
First add the whole number with the decimal number.
120 (1.02)² = 120 × 1.04
120 × 1.04 = 124.8
Now we have to Round to the nearest hundredth.
124.80 to the nearest hundredth.
To round 124.80 to the nearest hundredth consider the thousandths’ value of 124.8, which is 0 and less than 5. Therefore, the hundredths’ value of 124.8 remains 0.
Question 9.
450(1 + 0.05)2 ____________
Answer:
Given,
450(1 + 0.05)2

450 × 1.1025 = 496.125
Now we have to Round to the nearest hundredth.
496.125 to the nearest hundredth.
To round 496.125 to the nearest hundredth consider the thousandths’ value of 496.125, which is 5 and equal or more than 5. Therefore, the hundredths value of 496.125 increases by 1 to 3.
496.125 to the nearest hundredth is 496.13
Question 10.
900(1 + 0.03)2 ___________
Answer:

Now we have to Round to the nearest hundredth.
954.81 to the nearest hundredth.
954.81 to the nearest hundredth is 954.80
Question 11.
